Pape Malickou Diakhaté (born 21 June 1984) is a Senegalese former professional footballer who played as a central defender.

Having come through the Nancy youth ranks, he made his Ligue 2 debut on 20 October 2001, playing the first half of the 2–0 win over LB Châteauroux.

On 18 July 2007, it was announced that Diakhaté had signed a contract with Ukrainian club Dynamo Kyiv for a €4 million transfer fee.

A month later, on 1 September, he broke a collar bone in a match against FC Kharkiv, but once recovered returned to the team.

After Nancy's promotion to Ligue 1 in 2005, Diakhaté was also part of the Senegalese team that finished fourth in the 2006 African Cup of Nations.
